220-8209 - Miller Smith Silverline 220 Series Two-Stage Analytical Regulator, CGA 580, 0-15 PSI

Precision Control for Analytical Applications

The Miller Smith 220-82-09 Silverline High Purity Analytical Two Stage Regulator is engineered specifically for the rigorous demands of laboratory and analytical environments. When working with sensitive instrumentation such as gas chromatographs, thermal conductivity detectors, or flame ionization detectors, the stability and purity of your carrier gas are paramount. This regulator addresses these needs with a robust two-stage design that maintains a constant delivery pressure of 0-15 PSI, even as the supply cylinder pressure fluctuates from full to nearly empty. This eliminates the need for constant manual adjustments and ensures the integrity of your analytical results.

High Purity Construction

Contamination is the enemy of analytical precision. The 220 Series Silverline regulator features a stainless steel diaphragm which provides a non-contaminating surface for the gas stream, unlike rubber or neoprene diaphragms that can off-gas or absorb impurities. Additionally, the regulator includes a filtered seat that not only protects the internal mechanism from particulate damage but also enhances the overall purity of the gas stream. The body, bonnet, and gauges are fully nickel-plated, providing a clean, durable finish that resists corrosion and maintains a professional appearance in laboratory settings.

Operational Reliability and Safety

Designed to handle high inlet pressures up to 3500 PSIG, this regulator connects via a standard CGA 580 fitting, making it compatible with common inert gases like Nitrogen, Argon, and Helium. Safety is integrated into the design with a built-in capturable preset safety relief valve that protects downstream equipment from over-pressurization. Furthermore, the regulator is engineered to withstand vacuums generated during purging operations, a critical feature for maintaining system purity during cylinder changeouts. The large 2-1/2 inch gauges provide clear, easy-to-read monitoring of both cylinder and delivery pressures, ensuring operators can verify system status at a glance.
